= SAFETY nnvion non MOTOR VEHICLES-y To all whom it may concern;

Be it known that I, Monnrs SWARTZMAN,

a citizen of the United States, residing at Brooklyn, in the county of ,Kings and State W of .New York, have invented a new and useful Safety Devicefor Motor Vehicles,.0f

which the following is a specification.

The object of my invention is to provide a a device that will serve to prevent pedestrians who areaccidentally struck by moving motor vehicles from being touched ,by the wheels of said vehicles and from. falling under said vehiclesi While the design and construction at present" illustrated and set forth is deemed prefv The invention illustrated in the accom-- panying drawings, in which- Figure 1 is a perspective of the entire de-. vice as viewed from behind the bumper of thevehicleflhedevice. being attached to the front of said bumper; Fig. 2 is a perspective device; Fig. 3 is a side elevation, of [another component part; Fig. 4 is a side elevation of two other. component parts; Fig. 5is a side; elevation of another. component part; Fig. 6 is a diagramindicating the part of the floor of the vehiclethat isnear the operator; Fig.;7 is a view, from directly in front of the, vehicle, of.the devicewhen it is, v v I I tashedto the-ends of rod 6 at right angles and in the same ,plane- A wire rope 8 is not in operation; and Fig. 8 is a perspective view, from 'infront; of the vehicle, of the device when'it is in operation, details 13 and 13 of Fig. 7 being here omitted for the purpose of better illustrating the operation.

Similar numerals refer to similar parts throughout the several views.

' Figure 2 illustrates a simple construction of four thin rectangular walls or sides. It may be called a hollow cube with the top and bottom sides removed, rectangles a, 72, c,

d and e, 7, g, h, representing the open surfaces at the top and bottom. I shall refer to this construction as a framef The hole 1 is fifteen (15) inches directly to the left of point a", the center of the rectangle e,a, d,

It, and the hole 1 is the same distance to the right of point i. The holes 3* and 3? are similarly located on the rectangle 7, b, o, 9

and 'aredirectly behind his holes s ar andftiuiching point 2' is attached 'a coil spring 4. This co l spring 1s permanently All four holes are each one; and ions-half niches (1%) in diameter. Directly above attached to rectangle e, a, d, h. The height of thejframe, or, is equalto: twice the dis 'tanceibetween the ground and the bottom of the frame. The length ad isequal to the length o f a straight line drawn'between] the ends of the bumper to which the frame. is

attached. j The width at is slightly larger: I

the pl'ateflthat is e11 c l'osed than the width of in the frame.

Figure 3 illustrates a thin rectangular plate 15 of the same height as the frame. The length and the thickness of the plate are such as to enable itto inovefreely inside the walls of the frame and'yet be as close as, possible to these walls. The holes 2 and 2 are of the same size and relative location" as theholesof the frame. wire roped is attachedto the the plate.

Figure 4 illustrates two hollow tubes open at both ends. Each tube is one and one-half J inches in .diameter andqfour inches (4) long.

Referring to Figures theme 6 is and middle of the top edge of I inches (30) long and onehalf-inch (i in diameter. Therods 7 and 7 are each" one-half inch in diameter, their length. I

being such as toenable'each' to run through J i the hollow tubes and, all the holes of the plate and frame and yet. project ons-half inch beyond the outer rectangle.

These rods are rigidlyand .permanentlyatattached to the middle of rod'6." I

bled." The bumper 14 of the vehicle is. in attachment with the top part of the rectangle e, a, d, it, so that the topedge of the bumper is on a levelwith the top edge of the rectangle. The ends of the bumper curve away from but are directly behind and on a level with points, a and d, the toppoints of the rectangle. As regards the method of attaching the device to the bumper, Iregard cl'ampsas suitable forfthe purpose. However, this matter is'notapart of my invention, nor do I olaimit as such. e

As illustrated in the drawing, the tubes 9 and are permanently attached to the rec- 'the above-mentioned details properly assem tangle e, a, d, it, directly over its holes, so that each hole corresponds to, a hole or opening of a tube. The plate 15 is held in place inside the frame by the rods 7* and 7", which run through the tubes, then through the holes 1 and 1 of the frame, then through the holes 2 and 2 of the plate, then through the holes 3 and 3 of the frame, and then projecting one-half inch (5) beyond the outer rectangle f, b, 0, g. The coil spring 4t is attached to the rectangle e, a, (Z, k, at one ,end and to the middle of rod 6 at the other end. In Figure 1, there can be observed the wire rope 8 attached to rod 6 and rope 5 attached to the top of the plate 15.

Figure 6 indicates the floor of the vehicle underneath the knees of the operator. The rope 8 terminates and comes up throughthe floor about twelve inches (12) to the right of the operators right leg. To the end of the rope is attached a fairly large handle 10. Seven inches (7) to the right of this handle is a comparatively small handle 11, which is attached to the end of rope 5, which comes up through the fi0or.-

When the operator sees a pedestrian dangerously in the path of the vehicle, he pulls handle 10, thus pulling rope 8 and rod 6, thus pulling rods 7 and 7 back out of the holes of the frame and plate, whereupon the plate drops to the ground. When the operator releases the handle, the pull of coil spring a upon rod 6 causes rods 7 and 7 to spring back again into the four holes of the frame. i

As seen in Figure 8, the rods 7 and '7 are now directly above and touchingthe top edge of the plate. I Half of the plate is within the frame, as is illustratedby the dotted lines. The other half of the plate is outside and underneath the frame, covering up the front Wheels of the vehicle and the space between said wheels 12* and 12 which are illustrated by dotted lines. i

In order to pull up the plate, the operator first pulls back handle 10, thus pulling the rods 7* and 7 back into the tubes and out ofthe Way of the plate, The operator then pulls handle 11, pulling back rope 5, thus pulling up the plate. When its holes corespond to the holes of the frame, the operator releases handle 10 whereupon the rods 7 and 7" spring back into the holes of the frame and the plate. v a

Referring to Figure '4', the numerals 13 and 1?)" illustrate two curved metal strips permanently attached to the rectangle 7", b, c, 9, covering up its holes and the protruding ends of rods 7 and 7 The rods are thus protected from being accidentally pushed back by any object in front of the vention, and I do not claim it.

What I claim is A device of the character descr1bed,comprising a four-walled frame wlth two holes in one rectangle or wall andtwo other holes similarly placed in thev opposite rectangle or wall, a plate fitting into the frame said plate having holes corresponding to and placed similarlyto the holes of the frame, two short rods held together by a long rod said short rods running through the holes of the frame and I plate thereby supporting the plate, two hollow tubesenclosing and supporting said short rods,'two curved metal 1 str ps on the frame covering up the pro,-

truding ends of saidshort rods, means for pulling theshort rods out of the holes, means for allowing the short rods to spring back into theholes, and means for pulling up the plate from the ground to its normal position.
